統(tǒng)計計數(shù)、機械轉(zhuǎn)數(shù)、貨幣計數(shù)、流量計數(shù)、組選計數(shù)等，被廣泛地應(yīng)用于包裝、紡織、機械、印染等行

710A型累加電子計數(shù)器是我公司在德國亨斯特勒公司的710型累加電子計數(shù)器的基礎(chǔ)上，針對中國市場最新研制的計數(shù)器，它采用高度集成化的貼片元件，占用空間小，計數(shù)功能強，可由電壓脈沖、接近開關(guān)、光電開關(guān)、軸編碼器或機械觸點開關(guān)等信號驅(qū)動計數(shù)，計數(shù)頻率高。該計數(shù)器既可由前面板復(fù)位，又可外部電信號復(fù)位，使用簡便。其內(nèi)部特有的存儲器在掉電或關(guān)機后可將計數(shù)值保存十年且無需電池。6位紅色數(shù)碼管（LED）顯示，清晰度高，易辨識，不易受溫度及光線的影響，可用于間斷回零的計數(shù)工作，如統(tǒng)計計數(shù)、機械轉(zhuǎn)數(shù)、貨幣計數(shù)、流量計數(shù)、組選計數(shù)等，被廣泛地應(yīng)用于包裝、紡織、機械、印染等行業(yè)。產(chǎn)品系列及相關(guān)技術(shù)參數(shù)：型號 710A-P-L 710A-P-H 710A-N-L 710A-N-H 顯示 6位紅色LED顯示字高7mm 電壓（波動范圍：±10%） DC：12V～24VDC±10% 功率 1.5W 數(shù)據(jù)保持 10年輸入阻抗 22kΩ 門檻電壓高電平≥8 V，低電平≤2 V 極限電壓正負(fù)40V 計數(shù)（復(fù)位）信號頻率 30Hz 5kHz 30Hz 5kHz 計數(shù)（復(fù)位）信號觸發(fā)方式正沿正沿負(fù)沿負(fù)沿最小脈沖寬度 17ms 100μs 17ms 100μs 占空比 1：1 保護等級 2級前面板保護 IP54，DIN40050 后面板保護 IP00，DIN40050 抗干擾能力 2級（IEC801）工作溫度 -10℃~+50℃ 存儲溫度 -20℃~+70℃ 710A type electronic totalizing counter is a kind of new counter which is designed on the basis of the 710 type counter of the German Hyngstler company and is oriented to the chinese market. it used the highly integrated chip components with small space occupation and strong counting function, the counting can be made by the voltage impulse, approaching switch, optoelectric switch, shaft encoder or mechanical electrical contacting switch etc, it has high counting frequency. This counter can be reset by the front panel as well as by the outside electric signals, its use is easy. The unique inside memory will keep the counted value for 10 years after power failure or turning off of the power. The 6-digits-LED display has high resolution and is not easily influenced by temperature and light, it can be used for counting with interrupted reset such as statistic counting, mechanical rotation speed, currency counting, flow counting and group selection counting, it is widely applied in the industries such as packing, textile, machinery and dyeing and printing. Technical Parameters: Display 7 segments red LED Digit number 6 Digit height 7mm Supply power 12-24VDC Power consumption Vop=12V,Imax=120mA Outside fuse 250mA Data storage 10 years Input impedance 22K Ohm Min. inpulse period High level≥8V,low level≤2V Threshold voltage of counting(gate controlled) ±40V Input voltage of counting(gate controlled) 5KHz or 30Hz(depending on version) Frequency of counting(gate controlled) Positive edge or negative edge(depending on version) Trigger method of counting(gate controlled) 100us, forming time 17 ms Spacing ratio 1：1 Reset signal voltage high level≥8V Reset signal voltage limit +40V Reset signal trigger methom 1 positive edge Reset signal frequency 5KHz or 30Hz(depending on type) Min. period of reset signal 100us,forming time 17ms Protection class class 2 Front panel protection IP54，DIN40050 Back panel protection IP00，DIN40050 Anti-interruption capability IEC801.3 Operation temperature -10℃~+50℃ Storage temperature -20℃~+70℃
